FIELD OF THE INVENTION

The present invention relates to surgical devices, particularly to an circumcision equipment and more particularly to an advancing and self-locking device and a circumcision device, as well as an assembling method and an application method of the advancing and self-locking device; a built-in electric circumcision device and a valgus electric circumcision device; a built-in washer circumcision device and a valgus washer circumcision device; a blood vessel docking apparatus of a built-in or valgus circumcision device; a built-in or valgus graduated circumcision device; a knob opening device and a circumcision device, and an assembly method and a use method of the knob opening device; a positioning device for a built-in circumcision device; a knob opening/closing device of a circumcision device; a circumcision stapler and a U-nail thimble thereof; a prepuce circumcision stapler with an indication device, which is, more particularly, of a built-in type and a valgus type; an operation-visible circumcision stapler; an A-type valgus circumcision stapler; a B-type valgus circumcision stapler; a C-type valgus circumcision stapler.

BACKGROUND OF THE INVENTION

Refer to the advancing and self-locking device and a circumcision device, as well as the assembling method and the application method. The redundant prepuce or phimosis is one of the causes of male urinary system infections and sexually transmitted diseases. The redundant prepuce or phimosis can cause urinary tract infections, resulting in chronic prostatitis, with a series of symptoms, such as pains in back and waist, impotence and premature ejaculation. Therefore, the removal of the redundant prepuce is a good way to prevent these diseases.

Traditionally, surgical removal of the phimosis or redundant prepuce has the main technical points of removal of excess prepuce, hemostasis, and apposition suture of cut edges to skin. A postoperative patient cannot move around, suffers unbearable pain in each change of ointment and endures huge pain when stitches are taken out finally. In addition, incomplete ligating hemostasis will cause prepuce hematoma, thus requiring a surgical treatment again. Furthermore, since the prepuce removal and the hemostasis process are performed separately, the operation time is prolonged, and the patient's panic is exacerbated.

A therapeutic method of applying a laser and high-frequency electric surgical knife technology to circumcision has been developed at present. Although this therapeutic method substitutes for scissors cutting and makes a bleeding spot coagulated, the patient's tissues will be burnt and susceptible to infection.

Then, a circumcision device in which a prepuce incision is sutured using a suturing nail at one time was developed in this field. However, the circumcision device in the prior art seldom uses a special advancing and self-locking device, and therefore, the states (an initial assembly state, an assembly completion state, an initial use state and a use completion state) of the circumcision device cannot be accurately judged, and it is inconvenient to distinguish the used circumcision device from the unused. Accordingly, there is the risk of cross infection caused by repeated use among patients, easily resulting in misoperation and medical accidents.

Refer to the built-in electric circumcision device and a valgus electric circumcision device. The redundant prepuce or phimosis is one of the causes of male urinary system infections and sexually transmitted diseases. The redundant prepuce or phimosis can cause urinary tract infections, resulting in chronic prostatitis, with a series of symptoms, such as pains in back and waist, impotence and premature ejaculation. Therefore, the removal of the redundant prepuce is a good way to prevent these diseases.

A therapeutic method of applying a laser and high-frequency electric surgical knife technology to circumcision has been developed at present. Although this therapeutic method substitutes for scissors cutting and makes a bleeding spot coagulated, the patient's tissues will be burnt and susceptible to infection.

Then, a circumcision device in which a prepuce incision is sutured using suturing nails at one time was developed in this field. However, all of the circumcision devices in the prior art are manually driven or remotely pedal-driven. The surgical operation, especially the time and force for tapping out a U-nail, is very unstable due to features of manual drive. If being applied with excessive force, the U-nail may clamp off the prepuce tissue to cause failure of the surgery; or if the applied force is insufficient, the tapping of the U-nail may be incomplete, resulting in failure of both hemostasis and the surgery. In manual drive, the circumcision device has to be provided with two sets of driving structures to drive a circumcision knife and the U-nail, respectively. Once the two driving structures are uncooperative, phenomena will appear that the circumcision by the circumcision knife is completed while the U-nail fails to stop bleeding or the U-nail is tapped out while the circumcision is not completed, any of which has a great risk and brings pain to a patient.

Refer to the built-in washer circumcision device and a valgus washer circumcision device. The redundant prepuce or phimosis is one of the causes of male urinary system infections and sexually transmitted diseases. The redundant prepuce or phimosis can cause urinary tract infections, resulting in chronic prostatitis, with a series of symptoms, such as pains in back and waist, impotence and premature ejaculation. Therefore, the removal of the redundant prepuce is a good way to prevent these diseases.

Traditionally, surgical removal of the phimosis or redundant prepuce has the main technical points of removal of excess prepuce, hemostasis, and apposition suture of cut edges to skin. A postoperative patient cannot move around, suffers unbearable pain in each change of ointment and endures huge pain when stitches are taken out finally. In addition, incomplete ligating hemostasis will cause prepuce hematoma, thus requiring a surgical treatment again. Furthermore, since the prepuce removal and the hemostasis process are performed separately, the operation time is prolonged, and the patient's panic is exacerbated.

A therapeutic method of applying a laser and high-frequency electric surgical knife technology to circumcision has been developed at present. Although this therapeutic method substitutes for scissors cutting and makes a bleeding spot coagulated, the patient's tissues will be burnt and susceptible to infection.

Then, a circumcision device in which a prepuce incision is sutured using suturing nails at one time was developed in this field. However, the suturing nail/U-nail used in the circumcision device in the prior art is generally made of metal. After being tapped into the prepuce of a patient during a surgical operation, the metal U-nail will be in direct contact with the skin, which is likely to cause skin/tissue allergy, even infection, of the patient. In addition, if the U-nail is in direct contact with the skin and tissue of the patient, the possibility that the U-nail inserts into the tissue too deep during the surgery is very high, resulting in damages. Moreover, the U-nail may drop off in a postoperative period as friction between the metal U-nail and the skin/tissue is smaller, which may cause the failure of the surgery due to dropping off of the nail.

Refer to the blood vessel docking apparatus of a built-in or valgus circumcision device. The redundant prepuce or phimosis is one of the causes of male urinary system infections and sexually transmitted diseases. The redundant prepuce or phimosis can cause urinary tract infections, resulting in chronic prostatitis, with a series of symptoms, such as pains in back and waist, impotence and premature ejaculation. Therefore, the removal of the redundant prepuce is a good way to prevent these diseases.

Traditionally, surgical removal of the phimosis or redundant prepuce has the main technical points of removal of excess prepuce, hemostasis, and apposition suture of cut edges to skin. A postoperative patient cannot move around, suffers unbearable pain in each change of ointment and endures huge pain when stitches are taken out finally. In addition, incomplete ligating hemostasis will cause prepuce hematoma, thus requiring a surgical treatment again. Furthermore, since the prepuce removal and the hemostasis process are performed separately, the surgery time is prolonged, and the patient's panic is exacerbated.

A therapeutic method of applying a laser and high-frequency electric surgical knife technology to circumcision has been developed at present. Although this therapeutic method substitutes for scissors cutting and makes a bleeding spot coagulated, the patient's tissues will be burnt and susceptible to infection.

For the built-in type, a circumcision device in which a prepuce incision is sutured using suturing nails at one time was developed in this field. However, in the prior art, a circumcision cover only cooperates with a comprehensive cover and the circumcision and U-nail hemostasis are performed after clamping is completed. Since the position of the nail groove disposed in the comprehensive cover is always invisible, the prepuce blood vessel cannot be accurately positioned, and the U-nail in the U-nail groove cannot accurately correspond to the prepuce blood vessel during surgery. Thus, the surgical hemostasis effect is not good. Even the nail head of the U-nail may be right hammered into the blood vessel, and surgery risk is caused as blood cannot be punctually stopped.

For the valgus type, a circumcision device in which a prepuce incision is sutured using suturing nails at one time was developed in this field. However, in the prior art, a valgus circumcision device only adopts an upper cover and a lower cover cooperating with each other and an inner ring and an inner comprehensive cover cooperating with each other, and the circumcision and U-nail hemostasis are performed after clamping is completed. Since the position of the internally disposed nail groove is always invisible, the prepuce blood vessel cannot be accurately positioned, and the U-nail in the U-nail groove cannot accurately correspond to the prepuce blood vessel during surgery. Thus, the surgical hemostasis effect is not good, even the nail head of the U-nail may be right hammered into the blood vessel, and surgery risk is caused as blood cannot be punctually stopped.

Refer to the built-in or valgus graduated circumcision device. The redundant prepuce or phimosis is one of the causes of male urinary system infections and sexually transmitted diseases. The redundant prepuce or phimosis can cause urinary tract infections, resulting in chronic prostatitis, with a series of symptoms, such as pains in back and waist, impotence and premature ejaculation. Therefore, the removal of the redundant prepuce is a good way to prevent these diseases.

A therapeutic method of applying a laser and high-frequency electric surgical knife technology to circumcision has been developed at present. Although this therapeutic method substitutes for scissors cutting and makes a bleeding spot coagulated, the patient's tissues will be burnt and susceptible to infection.

For the built-in type circumcision device, a prepuce incision is sutured using suturing nails at one time. However, in the prior art, the positions of nail grooves arranged in a comprehensive cover will be invisible once the cooperation of the comprehensive cover and a circumcision cover is completed. Therefore, U-nails in the U-nail grooves cannot accurately correspond to prepuce blood vessels during surgery, resulting in a poor surgical hemostasis effect. Even the nail heads of the U-nails may be just hammered into the blood vessels, resulting in a surgery risk as bleeding cannot be punctually stopped.

For the valgus circumcision device, a prepuce incision is sutured using suturing nails at one time. However, in the prior art, the positions of nail grooves of an inner comprehensive cover in a lower cover will be invisible once the cooperation of an upper cover and the lower cover is completed. Therefore, U-nails in the U-nail grooves cannot accurately correspond to prepuce blood vessels during surgery, resulting in a poor surgical hemostasis effect. Even the nail heads of the U-nails may be just hammered into the blood vessels, resulting in a surgery risk as bleeding cannot be punctually stopped.

Refer to the knob opening device and a circumcision device, and an assembly method and a use method of the knob opening device. The redundant prepuce or phimosis is one of the causes of male urinary system infections and sexually transmitted diseases. The redundant prepuce or phimosis can cause urinary tract infections, resulting in chronic prostatitis, with a series of symptoms, such as pains in back and waist, impotence and premature ejaculation. Therefore, the removal of the redundant prepuce is a good way to prevent these diseases.

However, the circumcision device in the prior art seldom uses a special opening device, and therefore, the states (an initial assembly state, an assembly completion state, an initial use state and a use completion state) of the circumcision device cannot be accurately judged, easily resulting in medical accidents caused by misoperation. Even if opening and closing devices arranged on some devices in similar fields use elastic structures, the mold preparation cost is high, the assembly is difficult and damages or misoperation can easily occur in use. Furthermore, it is prone to errors even if the elastic structures are used for positioning.

Refer to the positioning device for a built-in circumcision device. The redundant prepuce or phimosis is one of the causes of male urinary system infections and sexually transmitted diseases. The redundant prepuce or phimosis can cause urinary tract infections, resulting in chronic prostatitis, with a series of symptoms, such as pains in back and waist, impotence and premature ejaculation. Therefore, the removal of the redundant prepuce is a good way to prevent these diseases.

A therapeutic method of applying a laser and high-frequency electric surgical knife technology to prepuce circumcision has been developed at present. Although this therapeutic method substitutes for scissors cutting and makes a bleeding spot coagulated, the patient's tissues will be burnt and susceptible to infection.

Then, a circumcision device in which a prepuce incision is sutured using suturing nails at one time was developed in this field. A plug or a knob needs to be provided at the rear end of the circumcision device and tightened through threads. Manual rotation is adopted in the prior art and whether the rotation is in place is subjectively judged only according to the rotation resistance, and therefore there is a great possibility of errors. When the rotation is too loose, it is possible that the front end of a connecting rod cannot be connected firmly or even loosened, and tends to drive towards a front cover body to produce a problem during a surgery, thereby resulting in surgery failure. When the rotation is too tight, it is possible to cause excessive threaded fit at the rear end of the connecting rod, thereby resulting in poor threaded fit at the front end of the connecting rod. The present inventor has proposed a method of judging tightening by arranging an alignment device on the outer surface. However, there is also a problem to only observe the alignment device arranged on the outer surface. Because the knob or plug cannot be tightened until it is rotated for a plurality of turns, it is impossible to determine which alignment of the alignment device is the best positioning state in the rotation process.

Refer to the knob opening/closing device of a circumcision device. The redundant prepuce or phimosis is one of the causes of male urinary system infections and sexually transmitted diseases. The redundant prepuce or phimosis can cause urinary tract infections, resulting in chronic prostatitis, with a series of symptoms, such as pains in back and waist, impotence and premature ejaculation.

Then, a circumcision device in which a prepuce incision is sutured using suturing nails at one time was developed in this field. However, a special opening device is seldom used in the prior art, and therefore, the states (an initial assembly state, an assembly completion state, an initial use state and a use completion state) of the circumcision device cannot be accurately determined, easily resulting in misoperation and medical accidents. Even though certain device is provided with an opening/closing device in the similar field, it adopts an elastic structure. Therefore, the mold preparation cost is high, the assembly is difficult, and damages or misoperation can easily occur during use. In addition, errors also easily occur when the elastic structure is adopted.

In the prior art, the circumcision device is driven by a handle. However, neither the circumcision device nor the handle is provided with an opening/closing device. Thus, infection and surgical failure even surgical accidents can be easily caused as the handle is wrongly operated once the circumcision device has not been disinfected, in place or in a surgical condition. Therefore, the inventor makes improvements by arranging an opening knob device to solve this problem and further arranging an opening/closing indication mark with respect to the problem that whether the circumcision device is in an opening or closing state after the knob is arranged cannot be intuitively confirmed. In arrangement of the opening/closing indication mark, paint or pigment is usually used for marking colors in the field of medical devices. However, the above chemical raw material will produce odor during production to pollute laboratories or production lines, and stripping-off can occur easily in the transportation or use process, resulting in failure of identification or pollution of the surgical environment.

Refer to the circumcision stapler and a U-nail thimble.

Then, a circumcision device in which a prepuce incision is sutured using suturing nails/U-nails was developed in this field. The circumcision device mainly relates to a built-in circumcision device and a valgus circumcision device which have been described in previous patent applications. However, there are following problems in the prior art.

(1) As a thimble and a U-nail may not be positioned completely when in a static state, the U-nail may not be located vertically upwards in a nail groove, but is inclined to the inner wall of one side of the nail groove.

(2) When the thimble and the U-nail are in a dynamic state, the U-nail may not be in a vertical upwards state when moving forwards, which is caused by vibration of the circumcision stapler as well as contact/collision/synchronous movement between the thimble and the U-nail.

(3) If the U-nail not vertically upwards is tapped out by the thimble, the U-nail will penetrate through prepuce or other tissues, or will be slant/inclined when being in contact deformation with a U-nail anvil/U-nail seat.

(4) The closure of the U-nail is incomplete, even fails if the U-nail cannot be tapped out vertically, so that accurate closure of a blood vessel cannot be realized. As a result, bleeding will appear, or even effective suture cannot be realized due to the deviation of a position where the nail is tapped out.

(5) During an implementation process of a poor-quality circumcision stapler, the U-nail may deform, fail to enter an expected location or even be tapped into the blood vessel, resulting in surgical failure and great pain in a patient.

Then, a prepuce circumcision device was developed in this field. For the built-in type prepuce circumcision device, a prepuce incision is sutured using suturing nails at one time. However, in the prior art, the positions of nail grooves arranged in a comprehensive cover will be invisible once the cooperation of the comprehensive cover and a prepuce circumcision cover is completed. Therefore, U-nails in the U-nail grooves cannot accurately correspond to prepuce blood vessels during surgery, resulting in a poor surgical hemostasis effect. Even the nail heads of the U-nails may be just hammered into the blood vessels, resulting in a surgery risk as bleeding cannot be punctually stopped.

For the valgus prepuce circumcision device, a prepuce incision is sutured using suturing nails at one time. However, in the prior art, the positions of nail grooves of an inner comprehensive cover in a lower cover will be invisible once the configuration of the inner ring and the cooperation of an upper cover and the lower cover is completed. Therefore, U-nails in the U-nail grooves cannot accurately correspond to prepuce blood vessels during surgery, resulting in a poor surgical hemostasis effect.

Then, a circumcision device was developed in this field. In the circumcision device, a prepuce incision is sutured using a suturing nail in one step. However, during a surgery using a conventional built-in circumcision stapler in the prior art, a front prepuce and most of a penis are exposed outside, so that the prepuce and the penis are vulnerable to injury or infection. A portion above a prepuce clamping portion of the built-in circumcision stapler is located outside the circumcision stapler, while a U-nail suturing position is located at the top of the circumcision stapler. Once hemorrhage caused by instrument failure or misoperation occurs, a patient is likely to be infected to cause a surgical accident. The built-in circumcision stapler has a built-in circumcision knife, and thus carries out cutting inside and nailing at periphery. In case of a redundant prepuce or the like, the possibility of cutting of overlapped tissues is high, causing pain and risks. In addition, if circumcision and hemostasis with U-nails are performed as soon as appropriate clamping is realized only through cooperation between an upper cover (upper comprehensive cover) and a lower cover (lower comprehensive cover/connecting cover) as well as between an inner ring (prepuce fixing hoop) and an inner comprehensive cover (U-nail top ring and/or thimble guide block), a prepuce blood vessel cannot be accurately positioned as a built-in nail groove is not visible. As a result, the U-nail in the U-nail groove cannot accurately correspond to the prepuce blood vessel during the surgery, so that a hemostasis effect is poor. Even, the head of the U-nail may be just hammered into the blood vessels, resulting in a surgery risk as hemostasis is not punctual. Moreover, in the existing technology, as the U-nail is directly hammered into the prepuce, the U-nail is likely to adhere with the prepuce and even U-nail cannot peel off punctually as the U-nail deeply penetrates into the prepuce in a process of waiting for necrosis and effluvium of the prepuce and peeling off of the U-nail after the surgery, causing severe pain to the patient.

Refer to the B-type valgus circumcision stapler. The redundant prepuce or phimosis is one of the causes of male urinary system infections and sexually transmitted diseases.

The built-in circumcision stapler has a built-in circumcision knife, and thus carries out cutting inside and nailing at periphery. In case of a redundant prepuce or the like, the possibility of cutting of overlapped tissues is high, causing pain and risks. In addition, if circumcision and hemostasis with U-nails are performed as soon as appropriate clamping is realized only through cooperation between an upper cover (upper comprehensive cover) and a lower cover (lower comprehensive cover/connecting cover) as well as between an inner ring (prepuce fixing hoop) and an inner comprehensive cover (U-nail top ring and/or thimble guide block), a prepuce blood vessel cannot be accurately positioned as a built-in nail groove is not visible. As a result, the U-nail in the U-nail groove cannot accurately correspond to the prepuce blood vessel during the surgery, so that a hemostasis effect is poor. Even, the head of the U-nail may be just hammered into the blood vessels, resulting in a surgery risk as hemostasis is not punctual. Moreover, in the existing technology, as the U-nail is directly hammered into the prepuce, the U-nail is likely to adhere with the prepuce and even U-nail cannot peel off punctually as the U-nail deeply penetrates into the prepuce in a process of waiting for necrosis and effluvium of the prepuce and peeling off of the U-nail after the surgery, causing severe pain to the patient.

Refer to the C-type valgus circumcision stapler. The redundant prepuce or phimosis is one of the causes of male urinary system infections and sexually transmitted diseases. The redundant prepuce or phimosis can cause urinary tract infections, resulting in chronic prostatitis, with a series of symptoms, such as pains in back and waist, impotence and premature ejaculation. Therefore, the removal of the redundant prepuce is a good way to prevent these diseases.

Traditionally, surgical removal of the phimosis or redundant prepuce has the main technical points of removal of excess prepuce, hemostasis, and apposition suture of cut edges to skin. A postoperative patient cannot move around, suffers unbearable pain in each change of ointment and endures huge pain when stitches are taken out finally. In addition, incomplete ligating hemostasis will cause prepuce hematoma, thus requiring a surgical treatment again. Furthermore, since the prepuce removal and the hemostasis processes are performed separately, the surgery time is prolonged, and the patient's panic is exacerbated.

A therapeutic method of applying a laser and high-frequency electric surgical knife technology to circumcision has been developed at present. Although this therapeutic method substitutes for scissors cutting and makes a bleeding spot coagulated, the patient's tissues will be burnt and susceptible to infection.

Then, a circumcision device was developed in this field. In the circumcision device, a prepuce incision is sutured using a suturing nail in one step. However, during a surgery using a conventional built-in circumcision stapler in the prior art, a front prepuce and most of a penis are exposed outside, so that the prepuce and the penis are vulnerable to injury or infection. A portion above a prepuce clamping portion of the built-in circumcision stapler is located outside the circumcision stapler, while a U-nail suturing position is located at the top of the circumcision stapler. Once hemorrhage caused by instrument failure or misoperation occurs, a patient is likely to be infected to cause a surgical accident. The built-in circumcision stapler has a built-in circumcision knife, and thus carries out cutting inside and nailing at periphery. In case of a redundant prepuce or the like, the possibility of cutting of overlapped tissues is high, causing pain and risks. In addition, if circumcision and hemostasis with U-nails are performed as soon as appropriate clamping is realized only through cooperation between an upper cover (upper comprehensive cover) and a lower cover (lower comprehensive cover/connecting cover) as well as between an inner ring (prepuce fixing hoop) and an inner comprehensive cover (U-nail top ring and/or thimble guide block), a prepuce blood vessel cannot be accurately positioned as a built-in nail groove is not visible. As a result, the U-nail in the U-nail groove cannot accurately correspond to the prepuce blood vessel during the surgery, so that a hemostasis effect is poor. Even, the head of the U-nail may be just hammered into the blood vessels, resulting in a surgery risk as hemostasis is not punctual. Moreover, in the existing technology, as the U-nail is directly hammered into the prepuce, the U-nail is likely to adhere with the prepuce and even U-nail cannot peel off punctually as the U-nail deeply penetrates into the prepuce in a process of waiting for necrosis and effluvium of the prepuce and peeling off of the U-nail after the surgery, causing severe pain to the patient.

Refer to the positioning device for a built-in circumcision device.

With respect to the above exiting technical problems, an objective of the present invention is to provide a positioning device for a built-in circumcision device. According to the positioning device, a positioning state of a knob and a connecting block can be accomplished uniquely and definitely by cooperating a positioning structure arranged on the rear end surface of the connecting block with a second positioning structure on the front-end surface of the knob. The specific technical solution is as follows.

A positioning device for a built-in circumcision device comprises a connecting block, a knob, a first positioning structure and a second positioning structure, wherein the rear end surface of the connecting block and the front end surface of the knob are positioned in a manner of cooperating with each other; the first positioning structure is arranged on the rear end surface of the connecting block; the second positioning structure is arranged on the front end surface of the knob; the first positioning structure and the second positioning structure cooperate with each other, such that the rear end surface of the connecting block and the front end surface of the knob are positioned in a manner of cooperating with each other.

Further, the first positioning structure includes one or more positioning convex points or positioning concave points; the second positioning structure includes one or more positioning concave points or positioning convex points; the positioning concave point and the positioning convex point cooperate with each other in a concave-convex manner, thereby accomplishing the positioning of the connecting block and the knob when they cooperate in place.

Further, the front end of the connecting block serves to connect a lower comprehensive cover; the rear part or the middle-rear part of the connecting block is provided with a transverse groove for allowing a sliding rod to be embedded, wherein the rear end of the sliding rod is flush with the rear end of the connecting block; the rear end of the connecting block is provided with a hole or a cylindrical groove which serves to connect the knob.

Further, the first positioning structure includes three positioning convex points which are uniformly arranged along the rear end surface of the connecting block.

Further, the knob is provided with a fixed surface which is provided with a cylindrical protrusion; the cylindrical protrusion serves to be inserted into the hole or the cylindrical groove of the connecting block.

Further, the second positioning structure includes three positioning concave points which are uniformly arranged along the circumference of the fixed surface of the knob.

Further, the outer surface of the connecting block is provided with a first positioning mark; the outer surface of the knob is provided with a second positioning mark; the first positioning mark serves to be aligned to the second positioning mark in rotation and is capable of being in an aligned state after the first positioning structure and the second positioning structure are positioned in a cooperating manner.

Further, an internal thread is arranged in the middle of the cylindrical protrusion and serves to be connected to an external thread at the rear end of the connecting rod in a manner of cooperating with each other.

Further, the front end of the connecting rod is provided with an external thread which serves to be connected to the rear end of a circumcision cover at the front end; the rear end of the circumcision cover is provided with a positioning rod; the positioning rod is provided with an internal thread which serves to be connected with the external thread arranged at the front end of the connecting rod in a manner of cooperating with each other.

Further, the positioning device further comprises a comprehensive cover whose front end serves for connecting the circumcision cover and whose rear end is connected to a lower comprehensive cover.

Compared with the prior art, the present invention has the advantages that the final positioning state of the connecting block and the knob is accomplished by adopting the positioning structures arranged on the end surfaces, which cooperate with each other, of the connecting block and the knob, thereby avoiding the error in the event of subjectively judging whether the positioning is accomplished by manual rotation. Especially by means of the cooperation of the positioning convex points and the positioning concave points, after the rotation is in place, the plug or the knob cannot be rotated even if a user tries harder, such that the positioning between the two structures is definite and unique. The following problems cannot occur: when the rotation is too loose, it is possible that the front end of the connecting rod cannot be connected firmly or even loosened, and tends to drive towards a front cover body to produce a problem during a surgery, thereby resulting in surgery failure; when the rotation is too tight, it is possible to cause excessive threaded fit at the rear end of the connecting rod, thereby resulting in poor threaded fit at the front end of the connecting rod.

Further, an alignment device which is arranged on the outer surfaces of the connecting block and the knob cooperates with the positioning structures. After multiple rotations and multiple alignments, the alignment device is just in an aligned state when the positioning structures are eventually positioned in a concave-convex cooperating manner. Therefore, an operator can further judge and determine a positioning state of the circumcision device by observing the state of the alignment device and according to a condition under which the alignment device cannot be further rotated even if a rotation force increases.

Compared with the prior art, through the structure of the valgus circumcision stapler provided in the present invention, a front prepuce and most of a penis can be accommodated during a surgery, so that the prepuce and the penis are protected from injury or infection. With the structure including the inner ring (the prepuce fixing hoop) and the inner comprehensive cover (U-nail top ring and/or thimble guide block), a portion above a prepuce clamping portion of the circumcision stapler is located in the circumcision stapler. The U-nail grooves are annularly formed in a relatively lower portion inside the inner comprehensive cover (U-nail top ring and/or thimble guide block), so that a U-nail suturing position is located inside the circumcision stapler to avoid hemorrhage caused by instrument failure or misoperation, avoiding a surgical accident arising from infection. The C-type valgus circumcision stapler provided in the present invention has the external circumcision knife, and carries out cutting outside and nailing inside. In case of a redundant prepuce or the like, the pain and risk caused by cutting of overlapped tissues is avoided. Through the blood vessel docking device arranged on the inner ring (prepuce fixing hoop), when the upper cover (upper comprehensive cover) and the lower cover (lower comprehensive cover/connecting cover) cooperate with each other and the inner ring (prepuce fixing hoop) and the inner comprehensive cover (U-nail top ring and/or thimble guide block) cooperate with each other, whether a prepuce blood vessel corresponds to the U-nail can be accurately determined, so that the final positioning of the inner ring (prepuce fixing hoop) and the inner comprehensive cover (U-nail top ring and/or thimble guide block) as well as the upper cover (upper comprehensive cover) and the lower cover (lower comprehensive cover/connecting cover) can be carried out after the blood vessel is positioned accurately, thereby greatly improving the hemostasis effect in the surgery. Preferably, the blood vessel docking grooves can be flexibly arranged to be in one-to-one correspondence with cooperative relationships among the U-nail grooves, the U-nails in the U-nail grooves and the intervals among the U-nail grooves, widths of the U-nail grooves, the U-nails and the intervals among the U-nail grooves, etc., so as to meet requirements of different circumcision devices and surgeries. Thus, the main surface of the U-nail can close the blood vessel, so that the hemostasis effect is excellent during the surgery, and the prepuce necrosis is accelerated after the surgery. More preferably, with the U-nail gasket, when being hammered into the prepuce, the U-nail will not adhere with the prepuce, thereby avoiding the pain in the patient caused by failure of the peeling off of the U-nail later.
